The units may be assembled in pairs for shipment or storage, the bottoms of a pair being removed and superimposed upon one unit and the second unit inverted thereon. A band-like wrapping 26 is placed about the pair of units between the frame so that the upholstery is completely covered and the two units collapsed and tied together by the ties 21 engaged overthe vertical arms 3 of the frames. This provides a shipping unit in which the frames are exposed to receiving the buffeting incident to shipment and storage, the upholstery being effectively protected.

In the embodiment of my invention illustrated in Figs. 5 and 6, the frame 30 is arranged with its angle facing inwardly, the upholstery securing rim 3| being disposed with its inner channel embracing the edge of the vertical arm of the frame, its outer channel facing upwardly to receive the edge of the upholstery skirt.

In the embodiment of my invention shown in Fig. 7, the frame 32 is arranged with its angle facing inwardly and downwardly. The rim 33 is of channel cross section and has its inner flange 34 extended to embrace and lap upon the inner side of the vertical flange of the frame and is spot welded thereto as indicated, its outer flange 35 being supported to receive and clampingly'engage the skirt ID of the upholstery.

In the embodiment shown in Fig. 8, the frame is arranged as in Fig. 7, the upholstery securing rim 36 having an angled inner flange 31 lapped upon and welded to the top of the frame 32, the channel facing upwardly to receive the upholstery, substantially as in Figs. 5, 6 and 7.

In the embodiment shown in Figs. 9, l and- 11, the frame 30 isjarranged with its angle facing upwardly and inwardly as in Figs; and 6. In Fig. 9, the channel sheet metal rim 38 has its inner flange extended into a horizontal arm 33 lapped upon and secured to the underside of the frame. In the embodiments shown in Figs. and 11, the sheet metal rim "has its inner flange extended into an arm 4| lapped upon the side of and secured to the frame 30, these embodiments being the same exceptas to positioning of the rim.

In the embodiment shown in Fig. 12, the rim 33 is substantially the same as that shown in Fig. 7, the inner flange of the rim being extended and lapped upon the inner side of the frame, the difference being that in Fig. 7 the frame is'disposed with its angle'facing downwardly and inwardly whereas in Fig. 12 it is disposed'with its angle facing upwardly and inwardly. The embodiment of Fig.-7 is, however, preferredover that shown in Fig. 12 for most uses for the reason that'in Fig. '7 the continuous binding afforded by the clamping rim serves to protect the portion of the upholstery most exposed to wear of the frame parts whereas in Fig. 12, the upholstery skirt is drawn around the angle of the frame. The clamping rim does, however, provide a continuous binding for the 'edge of the upholstery and receive the wear of the supporting frame.

My improvements enable the very rapid attachment of the upholstery and it is very securely retained, the edges being covered and prot cted from wear, avoiding the necessity for using gimp or other finishing strips. The structure is very strong and rigid even when made of comparatively light material.

I have not attempted to illustrate or describe certain embodiments of my invention and, as I stated, I have not attempted to show the parts in their relative proportions as a completed bed spring or box spring unit. It will be understood that while the structure is especially designed as a bed spring, or the commonly called box springs, 10

,it is desirable for automobile, truck, bus or car springs, particularly where relatively strong or sturdy structures are desired.

The structure is also well adapted for embodiment in the back springs and as an upholstery means for the back and spring upholstery of automobiles. I have not attemp ed to illustrate such embodiments or adaptations as it is believed that this disclosure will enable the embodiment or adaptation as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patcm, is: Y s
